Is there a way to automatically generate charts for all questions in a jot form or do you have to create each one manually in the report builder?

Is your question related to a Visual Report? 

How to Create a Visual Report with Your Form Submissions

When a Visual Report is created by default only two charts are added. You will have to manually create the charts for other fields. It is not possible to automatically create the charts for all form fields. 

Greetings! We're glad to inform you that we recently launched the new JotForm Report Builder. To check out its newest features, please click here.

The new version now allows you to add all supported questions at once upon report creation.
